Product Detail of - MEMORY HiCORDER MR8870
Product Category : Recorders, Data Loggers, Data Acquisition, Digital Osciloscope s
Series : Handheld Multi Channel Data Logger

A single instrument that can observe waveforms like an oscilloscope and record RMS value fluctuations

Hioki Memory HiCorders are high-speed waveform monitoring and recording devices that can simultaneously measure multiple quick-changing phenomena due to complete isolation between channels and from each channel to the ground. The MR8870-20 is a handheld data acquisition (DAQ) recorder built in with 2 analog channels and 2MW of memory, suitable for elevator maintenance, machine, motor and inverter fault analysis, testing and inspections.
